Trials FAVOR QFR Trials FAVOR QFR Versus FFR in Coronary Stenosisersus FFR in Coronary Stenosis
Two novel imaging systems that use angiographic information and hemodynamic modeling to emulate pressure-wire measurements were shown to provide diagnostic information about coronary stenosis in patients with angina that is on a par with that obtained through the more invasive fractional flow reserve technique. The studies — FAVOR II China and FAVOR II Europe-Japan — used different quantitative flow ratio systems to assess stenosis without a pressure wire and without inducing hyperemia.
